Referring to a static subclass element

Question

I want to have a sub keyword that would make the code below print value on execution. Does not exist, and I am wondering - is there an existing way to refer to a member of a subclass?

 class Main { static function foo() { echo sub::$variable; } } class Sub extends Main { static $variable = "value"; } Sub::foo(); 

Answer 1

I think you are looking for static::$variable . This is called Late Static Binding and is available since PHP 5.3.
